A free, privacy-first prorated rent calculator that turns any move-in and move-out date range into a clear, line-by-line rent statement — for tenants and landlords alike.
Move-in and move-out dates rarely line up neatly with the first and last of the month. When they don't, both sides of the lease end up asking the same question: how much rent is actually owed for a partial month? Prorated Rent Calculator exists to answer that question in seconds — with numbers both tenants and landlords can verify, instead of a back-of-the-envelope guess.
We built the tool we wanted to exist: completely free, with no signup or paywall, honest about the math behind every result, and flexible enough to match how leases are really written. Every calculation runs right in your browser — your rent amount and dates never leave your device — and the finished statement can be printed or saved as a PDF to keep everyone on the same page.
One partial month or a move-in on the 20th and a move-out on the 10th two months later — the range is split into per-month segments, each with its own day count and daily rate.
Switch between actual days in each month and the flat 30-day method landlords commonly use, and see both results side by side to match your lease.
A month-by-month calendar marks exactly which days are counted as occupied, so you can confirm the right dates went into the math before you pay.
Generate a receipt-style statement with the daily rate, days occupied and total due — print it or save it as a PDF to attach to an invoice or your records.
No account, no cookies required to calculate. Everything runs locally in your browser — rent amounts and dates are never uploaded or stored on our servers.
No signup, no paywall, no usage limit, and no calculate button — the statement updates the moment you change the rent or a date.
The math behind prorated rent is simple: convert the monthly rent into a daily rate, count the occupied days, and multiply. Enter your monthly rent, pick a move-in and move-out date, and the calculator does this for every month the range touches — dividing by each month's actual length (or a flat 30 days, whichever your lease uses) and itemizing the result line by line.
Both the move-in and move-out days count as occupied, which is the convention most landlords use. If your range spans several months, each month gets its own segment with the correct day count and daily rate, and the statement totals everything in one place. You can then print the statement or download it as a PDF — useful for move-in invoices, security-deposit conversations, or simply double-checking a property manager's math.
